This is not true in all cases. I have a 30 amp unit and my bedroom vent is prewired for a/c.

Ehh... Your trailer is 2nd AC prepped, considerably different than what he said. having prep for a 2nd AC without a 50AMP service is mostly useless, and would only have been done either by mistake, or custom order. The dealerships are not going to order rigs like this, they don't sell, and there is a reason for it.
